The dish volume is -15.3cc, which results in a 9.5:1 compression ratio. These pistons are forged from 2618 aluminum, a strong material commonly used for high-performance applications because it can withstand higher temperatures and pressures.

When installing these pistons, remember they are designed for specific engine builds and require careful attention to clearances and assembly procedures. It's always best to consult your engine builder or Mahle's specific installation guidelines to ensure proper fitment and performance.
